CAUTION: When using the ASD Fuel System Test, the Auto Shutdown (ASD) Relay remains energized for either 7 minutes, until the test is stopped, or until the ignition switch is turned to the Off position.

(6)With the ignition key in ON position, access the DRB II ASD Fuel System Test to pressurize the fuel system. Check for leaks.

(7)Reinstall air cleaner assembly.

FUEL PRESSURE REGULATOR

The fuel pressure regulator is mounted on top of the throttle body (Fig. 6).

REMOVAL

(1)Remove air cleaner assembly.

(2)Perform Fuel System Pressure Release proce-

dure.

(3)Disconnect battery negative cable.

(4)Remove pressure regulator mounting screws (Fig. 6).

WARNING: PLACE A SHOP TOWEL AROUND FUEL INLET CHAMBER TO CONTAIN ANY FUEL REMAINING IN THE SYSTEM.

(5)Reinstall air cleaner assembly.

FUEL INJECTOR

The fuel injector is installed in the top of the throttle body. The injector is covered by a cap.

REMOVAL

(1)Remove air cleaner assembly.

(2)Perform Fuel System Pressure Release proce-

dure.

(3)Disconnect negative cable from battery.

(4)Remove injector cap holddown screw (Torxhead).

(5)With two small screwdrivers, lift the top off the injector using the slots provided (Fig. 7).

Fig. 7 Removing Injector Cap

(6) Using a small screwdriver placed in the hole in the front of the electrical connector, gently pry the injector from the pod (Fig. 8).

INSTALLATION

(1)Apply a light coating of clean engine oil on the O-rings.

(2)Place assembly in the pod. Align the injector wiring terminals with the injector cap fastener hole (Fig. 10).

Fig. 10 Fuel Injector Installation

(3)Install injector cap with locating notch aligned with the locating lobe on the injector (Fig. 11).

(4)Push down on the cap to ensure a good seal.

(5)Rotate the cap and injector to line up the attachment hole (Fig. 12).

(6)Install injector cap holddown screw (torx-head screw). Tighten screw to 4-5 NIm (35-45 in. lbs.) torque.

(7)Connect negative cable to battery.

(2)Disconnect negative cable from battery.

(3)Disconnect AIS motor connector.

(4)Remove AIS motor mounting screws (Torx head screws, 25 mm long).

(5)Remove AIS motor from throttle body housing. Ensure O-ring is with AIS (Fig. 14).

the DRB II Actuate Outputs Test, AIS MOTOR OPEN/CLOSE (battery must be connected for this operation).

(2)Install new O-ring on AIS.

(3)Install AIS motor into housing, ensuring the O-ring is in place.

(4)Tighten mounting screws to 2 NIm (20 in. lbs.) torque.

(5)Connect harness electrical connector to AIS mo-

tor.
